Start with the symptom
What is blocked or draining slowly?
The visible symptom helps route the enquiry. It does not confirm where the blockage is or which method will be appropriate.
Blocked toilet
The bowl rises, drains slowly, will not clear or threatens to overflow.
Bath or shower blockage
Standing water, slow drainage, gurgling or odours affect a bathroom waste.
More than one fixture
Several connected fixtures are slow or backing up, suggesting the issue may extend beyond one trap.
Service scope
What the blocked-drain visit can cover
This page focuses on domestic internal drainage: the sink, basin, bath, shower, toilet and their accessible waste connections.
✓Review the affected fixture, water level, odour, gurgling and recurrence
✓Check accessible traps and internal waste connections where suitable
✓Explain the proposed internal unblocking route before work proceeds
✓Test drainage after the agreed work and explain any remaining warning signs
Within this page
Internal fixture blockage
A blocked sink, blocked toilet, slow bath, shower or accessible internal waste is the intended route.
Assessment first
Several fixtures or repeated backup
Multiple affected fixtures, recurring blockages or external signs may indicate a wider issue that needs further investigation.
No unverified equipment claim
CCTV surveys, high-pressure jetting, drain lining, excavation and structural drain repair are not promised on this page. If later evidence confirms those capabilities, they should have clearly defined service routes.
How it works
From first contact to flow testing
The process separates a simple fixture blockage from symptoms that may extend beyond the visible fitting.
1
Describe what is affected
Share the fixture, visible water level, when the problem started and whether any other waste is slow.
2
Check urgency and access
Overflow, sewage, the only usable toilet and any water near electrics are separated from routine enquiries.
3
Assess the likely route
The affected fitting and accessible internal waste route are checked before the proposed scope is explained.
4
Agree, clear and test
A clear quote is agreed first. Completed work is tested and any signs that need further investigation are explained.
Before help arrives
Reduce the chance of an overflow getting worse
Small, safe actions can limit additional waste water while the correct route is arranged.
01
Stop adding water
Avoid running connected taps, appliances or repeated flushing when the water level is rising.
02
Do not mix chemicals
Do not combine drain products or use an unidentified chemical. Tell the person attending if any product has already been used.
03
Keep the area clear
Keep children and pets away from waste water. If water is near electrics, do not enter or touch affected equipment.
Pricing and standards
What can affect a drain-unblocking quote?
No fixed price is shown because the affected fixture, access, severity, recurrence and need for additional investigation vary.
Fixture and access
The location of the blockage and safe access to the trap or waste connection influence the proposed scope.
Severity and recurrence
A local restriction differs from several affected fixtures or a blockage that returns after being cleared.
Clear commercial terms
No call-out fee. You pay for agreed labour and materials after receiving a clear quote before work begins. Cash, credit card and debit card accepted.
Testing and aftercare
Relevant completed work is covered by a 12-month workmanship guarantee, subject to the agreed scope and written terms. Any signs outside the agreed internal work are explained as a separate next step.
Service information
Choose the correct route before getting in touch
These are practical routing notes, not an online diagnosis or a substitute for inspection.
Blocked toilet or toilet fault?
Use this page when waste is not clearing. For cistern, flush, fill, seal or installation faults, use the toilet repair route.
Not sure if it is urgent?
Active overflow and sanitation risks belong on the emergency plumber page. Slow drainage without overflow can start here.
